i V This inventionrelatesto. silos, a lth9 1g h equally applicable to corn cribsorl gran-ar 'es.

The primary objectoitheinvention isto set' forth-and manifested in the cou rse of the following description.

Inthedrawings:

Fig. 1 is a fr'ontelevat ion of the invention;

Figs. 2, 3, 4, and 5 are enlarged sections on the lines'22,"33, l -4, and 5 -5 respectively of Fig.1. r i

Referring to Fig. 1 it will be seen that there are short-units 1 having two panels 2 and 3,

the units being formed of wood ior' metal frames'havingcross pieces 4 which define the panels 2 and? "Adjacent panels have their endsabutting and are secured by bolts and nutsre. Alternating with the short units 1 are long units 6 composed'ofthr'ee panels 7,.

8, and 9, the long units also'being constructed of wood or metal frames f and have their panels, in alignment with thecrosspieces 4 of the short units 1 and-With. the adjacent superimposed ends of two adjacent short units. The sides of the short and'long units'are also bolted together as: indicated" at '12. I Refer-v ring to Fig.4 of the drawings it willbe' seen that the frames of which the units are formed are covered with metal sheathing 13, the

u edges. of which are inturned at" right angles as indicated at 14 and are embedded in cut-- out portions formed therefor in the frames 1 and maybe secured ornailed in position as indicated at 15. Any suitable packing strips 16 may be interposed between adjacent units ""to seal the joints. From the foregoing it the invention aims to pro cross pieces 10 and 11, which definethe will be seen that'the frames of t he are not only strengthened and reinforced by the metal sheathing but'further that a siniple and economical construction of units is provided. Theto'p of the structure is formed of similar units 17 which are generally of segmental form which latter are bolted to'- get-her as shown at 18. A door 19, which may be secured in an opening 20, in any suitable manner is employed, the opening being formed in one ofthe top sections 17'. Y

A door frame or doorway 21 is provided and I is interposed between adj ac'ent vertical tiers of the units and is bolted thereto as shown "at 22. Cleats 23 are secured by fastenings 24 to the inner faces of the sides of the door frame'and are provided with cut-outs 25:that

, extend through the tops of the cleats and are formed to afford substantially V-shaped seats 26 at the lower parts of the cut-outs.

There are a series ofsuperimposed doors for the doorway each composed of a metal plate 27 'to eachpfuwhich. is secured a cross bar 28 by means of bolts 29, the 'cross' bars being provided with V-shaped portions 30 that correspond to the seats 26 and conformably engage therein as shown, particularly in Fig. 2.. As shown in ig. 3 the sides of the metalplates'27 are turned outwardly as indicated 1 t se tigh ag n t h m l p ate 13 of the units. As shown in Fig. 2theu-p' her ends o h p t s 27 e tu n d in ar 1y as indicated at 32am engage against the adjacent cross pieces. ofthe adjacentunits and inturn 'areengage d by the bottom edges the metal-plates 2? of the next adjacent upper ,doorsection. v In this Wayi fit will be noted that tightjoints are formed between the adjacent door sections and theadj'acent metal plates of theunits, thus affording a metal-to-metal contact or joint throughout the boundary offeach' of the door sections;

the .pressure of th'e' silage obviously 'maintainingthejoints tight. It will also beapparent thatthe door sectionscan lee-easily and quickly {removed and applied,and lH I"( 3 i movingsameare merely liftedfupwardly. v w the 1 352 9 o heirf eat' er i A upon thefloor can be moved outwardl'yin a lateral direction and can be easily secured in position by reverse movements.

It will be further understood that each unit is transversely curved so that the entire assemblage affords a structure circular in cross section.

Preferably, in assembling, only sufiicient bolts are employed to temporarily hold the structure together, cables 33 being then secured about the structure and are drawn taut by means of turnbuckles 34. Of course if desired the bolts 5, 12, and 22 can remain in plates overlapping the doorway at their sides position and be tightened. As shown in Figs. 3, 4,, and 5 the metal plates of the units form virtuallyacontinuous metallic lining for the entire structure, while the roof units have. their metal coverings exposed and form a sealed roofing for the silo.

V The metal plates formingrthe bodies of the doors, are of sufficient flexibility so as to. respend to the pressure of the silage and thereby assure tight metal-to-metal joints.

I What is claimed is V 1. In a structure of the type set forth. a series of transversely curved units each composed of an open rectangular frame, metal sheathing extending over said frameand having the edgeportions thereof turned at right angles and secured to the adjacent edges of the frame, and means to secure adjacent units together in superimposed and side to side engagement and with the sheathing forming a substantially continuous lining for the structure and with the frames exposed on the exte-j rior of the structure, said securing means being disposed exteriorly of the frames.

2. In a structure of the type set forth, a seriesof transversely curved units each com posed of an open rectangular frame, metal sheathing extending over said frame and having. the edge portions thereof turned at right an es and secured to the adjacent edges of the frame, and means to secure adjacent units together in superimposed and side to side engagement and with the sheathing forming a substantially continuous lining for the structure and with the frames exposed on the exterior of the structure, said securingmeans being disposed exteriorly of the frames, said units being composed of alternating series of long and short frames, the horizontal joints between adjacent short units occurring intermediate the ends of the adjacent long units.

3. In a structure of the type set forth, a doorway having substantially V-shaped aligned seats on the inner faces of its oppositesides, and a series of door sections each composed of a metal plate and a transverse bar secured to the plate between its ends and having corresponding V-shaped parts receivable in the seats, wall forming units secured to the sidesof the doorway, said plates having their sides turned at an angle and engaged with adjacent units and having their tops tween the ends of the latter and having portions engageable in the seats to hold the doors against outward movement, and being removable from the seats by upward movement out of the seats and then outward movement, said and one other at their ends and being flexible so as to respond to the pressure of the silage and effect tight jointswiththe parts against wh'ichthe plates engage.

- 5. In a silo or the like, a body having a doorway, a series of doors, and means to removably mount the doors in the doorway, said'doors having portions which extend an appreciable distance beyond the doorway at their sides andtop for engaging the inner face of thebody,and which overlap one another at their ends, said portions of the doors being flexible so as to r'espondto the pressure of the silage andto effect tight joints with the parts engaged by said door portions.

6. In a silo or thelike,a metal-lined body, a doorway, doors and means to. removably mount the doors in the doorway, said doors having bodies composed of flexible metal plates which overlap, and engage the lining at their sides and top and one another at their endswhereby to form tight metal-to-metal joints at all of the bounding edges of the do,ors, V

7 .-In a silo, abody having a doorway, a serles of doors and means to removably mountthe doors in the doorway, said doors T" having bodies formed of flexible metal plates which engage the silo body at their sides and which havetheir upper endsturned inwardly to also engage the silo body, the lower ends of the plates being engaged over the inclined 311? upper ends of the plates whereby to form tight metal-to-metal joints ,at all of the bounding edges of the doors.

8. In a silo or the like, a series of superimposed units having side-to-side engagement, with adjacentunits, each unit being composed of an open frame, a metal covering extending over the frame and having its free edge portions bent at substantially right angles to form flanges, the flanges of one unit being adapted to engage the flange of the next adjacent unit andmeans for securing the unlts and thereby the opposed flanges together to form tight metal-to-metal joints at theedges of each unit;
